I use getScript() to load remote Google jsapi and then load a local script that requires access to Google jsapi:

$.getScript(

remote-jsapi,

getLocal());

function getLocal(){$.getScript(local-script)}

In IE6 & IE7, the local script, which calls google.load(), runs too early resulting in error: "google is undefined"

I can prevent "undefined" error by setting a timeout that gives IE6 & 7 time to load jsapi before calling google.load in my local script.

IE8 & FF handle callback correctly.
